Transparent bridge between two devices

How to create a transparent bridge between two devices (2 pcs esp-07) by using AT+SAVETRANSLINK command? Or is it impossible so far?

Hi,

For example, ESP8266 A to be softAP, ESP8266 B to be station which connected to A.

A create a TCP server, B runs as TCP client and use "AT+SAVETRANSLINK" to save a transparent link to A.

Creating a TCP server requires multiple connection (CIPMUX=1) and can be set only in normal mode (CIPMODE=0). This means that transparent transmission runs only in one direction (from station to softAP), am I right? I think the question is about the possibility to build a sort of serial cable replacement with two ESPs and then transparently write to A-side and read from B-side (and vice versa):

[UART RX,TX,RTS,CTS]<->[ESP A] ... [ESP B]<->[UART RX,TX,RTS,CTS]
